逢坂 泉

"Good grief…they’re noisy. I apologize for my loud brothers.”

Izumi is oddly calm for his age and ignores the things his brothers’ make a commotion over. He’s generally quiet, and the few times he says something it’s cruel. He’s surprisingly sensitive and stopped going to school because kids bullied him for only having one parent. He was, of course, against the annoyance brought on by a remarriage.
